Shyster Dale Vince is STILL pushing his nonsense about green gas.
As a heat pump user in a house at EPC band C (near top), I can confirm that indications are, with appropriate tariff, heating bills are lower but the house is cosier than when we used gas only replacing few rads.
Sure there are logistical problems for roll out & heat pumps aren't the only solution but so called green gas (grass to gas FFS) is not a solution.
